THREAD PARTER AND CLAMP.

Application led January To all whom t may concern.'

Be it known that I, ALONZO E. RHoADEs, a citizen of the'United States,residing at Hopedale, inthe county of Vorcester and State ofMassachusetts, have invented an Improvement in Thread Parters andClamps, of which the following description, in connection with theaccompanying drawings, is a specification, like characters on thedrawings representing like parts.

' This invention relates to thread parters and clamps for use in fillingreplenishing looms.

It is now the general practice to provide filling replenishing loomswithA a shuttle feeler having associated therewith a thread parter andclamp for parting the filling between the shuttle and cloth selvage whenfilling replenishment is effected and positioning the end of the lllingleading to the cloth selvage for the action of the temple thread cutter.'Ihe shuttle feeler thread cutter or parter is now ordinarily formed ofa fixed and a movable member, the latter of which is actuated by the laywhen the shuttle feeler is in its rearward shuttle lfeeling position,and mounted on the shuttle feeler at the side of'the thread parter thereis usually a thread cla-mp between which and the movable thread cutteror parter the thread end leading to the cloth selvage is yto be clampedand held, so that when the shuttle feeler returns to its frontwardposition the end leading to the cloth selvage will be presented to thetemple thread cutter.

As heretofore ordinarily constructed, the thread clamp and movablemember of the thread parter have been arranged face to face, that is,the side of the thread parter bore against the side of the thread clamp,with the result that when the parter was actuated to part the thread,the end of the filling leading to the clothl selvage would fail to beclamped between the parter and clamping member. or the movement of thesemembers past each other during the kclamping operation would causelbreakage of the thread at the clamp and consequently the end of thefilling leading to the cloth selvage would not be positioned'for theaction of the temple thread cutter.

One of the objects of the present invention is to provide a threadparter and clamp wherein a space is provided between the side faces ofthe parter and clamp to r6- 15, 1925. Serial No. 2,573.

ceive the end of the filling and thereafter clamp the filling end bymovement of the parter and clamp relatively in a lateral direction topinch the thread between them.

In accordance with the present invention, the clamping member underliesthe thread leading from the shuttle to the cloth selvage when theshuttle .feeler is in its rearward shuttle feeling position, and uponactuation of the parter to partthe thread the clamp itself is moved inan opposite direction to lift the filling end that it may be clampedbetween the parter and clamping member before the filling is cut orparted. Y

The invention and novel features of the structure will best be madeclear from the following description and the accompanying drawingsshowing one good form thereof.

The shuttle feeler may be of any usual character and mounted formovement into its rearward shuttle feeling position on call' forreplenishment ofiilling. As'shown, the loom frame has'secured thereto abracket 1 which may be adjustably mounted onv the 'loom frame by a bolt2 entering a slot 3 formed n the bracket member. The shuttle feeler 4 isshown as mounted for rocking movement on a stud 5 extending from thebracket 1 as usual in this type of shuttle feeler, and extending fromthe bracket 1 is a guide 6 for directing the movement of the shuttlefeeler as it is turned to and IQIX! its shuttle feeling position,

Extending from the shuttle feelei ll-is a pin 7 which is engaged betweenthe two arms Sand 9 for moving the shuttle'feel'elr to' and frbm' its;'rearward position, usual in this type of" mechanism, The arms 8 and 9are connected to the transverse or rock shaft (not shown), but sincesuch Vdetails form no essential part ofthe present invention and are nowwell uiiderstood'in the' art, they' are not-hereinafter described. v

The shuttle feeler l has its end portion 10 extending rearwardly d andisl provided with the-usuall opening,` 11 for engagement with the'shuttle, Yprovided thev latter is not properly boxed, and securedto theinner face of the end Vportion 10 of Vthe kshuttle feeler is the lixedthreadpart'er '12, which may be conveniently formed as a blade'securedas usual to theshuttle feeler. The cutting edge portion-Hof the fixedblade 12 is shown `as slightly below vthe surface 111 y"of the shuttlefeder, on whichthe filling end a is supported when tlie shuttle feeleris in its rrearward feeling position. y I A "'Pivotallymounted on thepinr15 extending laterally from the end l0 of the shuttle feeleristheimovable threadA parter 16, the frontwardly extending end portionof which is provided with an actuating member or toe 17 -`which-isadapted tobe sti'uclrby thejlay or a,1 lpart f carried1 thereby, toactuate the movable member of the parterto part the thread a betweentheshuttle 18 and cloth Aselvage.

A I

The threa-'dparter 1.6 has a rearwardly extending end portion A24 whichAunderliesthe thread a -when the shuttle feeler "with V the threadparterand clamp are moved to rearward ^fi"1nction-ing position. v

The 'clamping member 19x is provided with. aslot Q5 into which extends apin 26 projecting from the movable thread parter 16,

the construction being such that when the thread parier 16 1s actuated,as hereinbefore described7 it `will impart to the thread clamp 19movement in an opposite direction,

to therebylift the filling thread a as the threadf parjter V'isactuated. y

1f'n accordance 'with the present invention, the thread parter and clamphave a relative lateral movement to first provide a space betivemovement of theparterand clamp until the thread tobe partedandclampedhas been placed' in a'spa'ce between'the parter 16 'and the clamp 19.

In the present instance of the invention, as

indicated in Fig. 5, the clamp 1,9 is provided with a spacer 29 whichi'iorinally: b'e'ars'upon the face ofthe parter 16 and 'maintains thepartei1 16 and clamp1f9'i'n separated relation Ytoy provide 'a space 30betweentl'ie'm for the reception ofthethread to be partedand Pf clamped,and 'to permit the parterand clamp to be moved relatively in Aa lateraldirection to clamp thethread when, once'it has been placed in a spacebetween theftwo `and preferably before the thread lis parted,tlien'iovf' ableI member 16 ofthe part'er is VVprovided with` a recessBlv'lwliich, 'asY the plarter 16 is actuated Itorlpiart thetlireadfcomes opposite v@thespacer 29'and permits rthe parter and clampto move laterally into` thread pinchingposition, as indicated in Fig. 1.v lie spacer 29 shown as rformed byaliea'died bolt or rivet passedthrough theclamp 197 as a convenient nieanspf forming the spacer to holdthe *clamp andvparter in 'separated L relation during the preliminaryentering of thetliread between thet'wo, and the recess 3.1 is shown asformedby a depression 'in' the adjacent .side face of the parter'16, theconstruction bein'g such that when theshu'ttle feeler is in its rearwardfeeling position and the filling to befparted is restingr in the recess11 of the shuttle feeler :and on top of the'underlying portionQi oftheclamp and .the partei is factuated7 the A,thread will zbe lifted by theclamp19 and vpass freely into the open space/*3Q lbetween .the parterand clampas the parter performs yits parting function5 whereupon,orfpreferably kjust prior tothe parting of theythr'ead74 ther recess 31of the parter 4will pass infront of Vthe spacer *'29ya`nidl permitrelative lateral movement of the Yparter and clamp* to ypinch or them.,After the 'ltlii'zead has thus been clamped beween the parter andclamping member' and is securely held, the parter 16 will part thethread by coact-ion with the fixed parter member l2, as indicated inFig. 4.

By preliminarily entering the filling to be parted in the space betweenthe parter and clamp and then causing relative lateral movement of theparter and clamp to pinch and hold the thread, all liability of thethread being broken between the parter and clamp is avoided and thefilling end leading to the cloth selvage will unerringly be moved intoposition forV the action of the temple thread critter.

Preferably the thread will be clamped, as described, before it isparted, but these two operations may take place simultaneously ifdesired.

As indicated in Figs. 2 and 3, it will be noted that the filling threadis first located in the space between the parter and clamp, as theformer moves in the performance of its cutting function, and thatthereafter the relative lateral movement of the parter and clamp willhold or pinch the Filling already placed between them before the threaditself is parted.

The lay 32 may if desired be provided with an opening 33 for theentrance of the end of the shuttle feeler parter and clamp when thesemembers are moved to their' rearward functioning position.

Extending from the front portion of the movable member 16 of the parteris a pin 34 which serves in connection with a swinging trip member 35 toopen the parter as the shut-tle feeler moves towards rearward position,and after the parter has been closed and the thread has been clamped, asdescribed, such pin 34 will pass the trip 35 by swinging the latter asthe shuttle feeler moves to its front position. y

As indicated, in the present form of the invention the trip 35 ispivotally mounted at 36 on an arm 37 which may be conveniently securedto the bracket 1, as usual in this type of mechanism. The trip 35 has alateral projection 38 adapted to engage a stop 39 on the arm 37 to limitits rearward swinging movement but permit frontward swinging movement ofthe trip.
